You have computers, tablets and smartphones, so you know what USB cables are. They're the cables with a flat rectangular connector on one end and typically a smaller connector on the end. You might use one to connect your printer to your laptop, or to charge up your smartphone.
There's a new generation of USB cables called USB Type-C, or just USB-C. It looks the same on both ends and, in fact, you can plug either end into your devices. So, it will make it simpler to connect your devices.
Plus, it's powerful. For instance, you can use Type C to charge 15-inch laptops, which use about 60W of power. The USB-C has a top speed of 10GB/second and output power of 20V(100W).
That's all good. But, as it turns out, not all USB-C cables are the same, according to Google engineers, who are reviewing third-party USB-C cables that Amazon is selling. They say some third-party USB-C cables "flaunt the specification."
